Delimitação de parques aquícolas para o cultivo da "ostra nativa" Crassostrea rhizophorae (Guilding,1828) no litoral Norte do Estado de Pernambuco - Brasil

Abstract

This work aimed to delimit collective aquaculture areas to the “native oyster” Crassostrea rhizophorae farming, as part of the Mariculture Development Local Plan in the Pernambuco’s north coast. Indicators were identified, selected and hierarquized to enable the elaboration of a conceptual model subsidizing the selection process of potential oyster farming areas. Depth measurements were realized in transversal sections of the estuarine channels using ecobathimeter linked to a GPS (Global Positioning System) and a Palmtop. In the of aquaculture area demarcation was used eight environmental indicators, seven socioeconomic and five of production/logistics to subsidize the selection process of the oyster farming potential areas. Three preferential areas were delimited, in which six collective aquaculture areas were demarcated, being three in the municipality of Goiana (estuary of the river Itapessoca), two in Igarassu (estuary of the river Timbó) and one in Itapissuma (Santa Cruz channel), where 263 individual aquaculture areas could be inserted, totalizing 77,2 ha of collective aquaculture areas.
